When I think of Tom Baker, my thoughts are drawn to the time he spent as Doctor Who. So, for the 'Today's Tune', I picked the song "Who Are You?" by England's heavy metal pioneers, Black Sabbath. It was first released on the 'Sabbath Bloody Sabbath' album in December of 1973. The album tour began in January of 1974, the same year Tom Baker began his tour as the Doctor.
